“…In contrast, activity in the right IPS did not modulate significantly during task performance. This retrieval-phase dissociation of left and right IPS is consistent with left lateralization of retrieval success effects, which cannot be attributed to the use of linguistic stimuli (Sanefuji et al, 2007; Shannon and Buckner, 2004). …”

Optimal memory retrieval depends not only on the fidelity of stored information, but also on the attentional state of the subject. Factors such as mental preparedness to engage in stimulus processing can facilitate or hinder memory retrieval. The current study used functional magnetic resonance imaging (fMRI) to distinguish preparatory brain activity before episodic and semantic retrieval tasks from activity associated with retrieval itself. A catch-trial imaging paradigm permitted separation of neural responses to preparatory task cues and memory probes. Episodic and semantic task preparation engaged a common set of brain regions, including the bilateral intraparietal sulcus (IPS), left fusiform gyrus (FG), and the pre-supplementary motor area (pre-SMA). In the subsequent retrieval phase, the left IPS was among a set of frontoparietal regions that responded differently to old and new stimuli. In contrast, the right IPS responded to preparatory cues with little modulation during memory retrieval. The findings support a strong left-lateralization of retrieval success effects in left parietal cortex, and further indicate that left IPS performs operations that are common to both task preparation and memory retrieval. Such operations may be related to attentional control, monitoring of stimulus relevance, or retrieval.

“…However, a perfused rat brain model showed that oxy-Hb was the most sensitive indicator of these changes (Hoshi et al, 2001). In the present study, we only found effects for total-Hb, suggesting that total-Hb may be a better marker of cortical neuronal activity than oxy-Hb for event-related NIRS, as previously suggested (Sanefuji et al, 2007). A study on temporal hemodynamics with event-related design also demonstrated that cerebral blood flow measured by arterial spin labeling MRI had the highest correlation with total-Hb monitored by NIRS (Huppert et al, 2006).…”

“…Analyses of both the raw data and the DPF-independent indices (i.e., the proportion of Hb changes under visual and auditory conditions) produced similar results, but may vary under specific circumstances. We previously reported that activation differences between Hit and CR in R15 (Sanefuji et al, 2007) were significant for the indices (p = 0.016, paired Student's t-test), but not for the raw data that were highly scattered and skewed (p = 0.053, Wilcoxon's signed rank test). The index-based analysis may be beneficial for statistically modest results (Meeting of Japan Optical Functional Brain Imaging Society, 2006, Tokyo).…”

“…Because analysis of raw data may be problematic, we utilized the method introduced by Sanefuji et al (2007). The activations in visual and auditory conditions were represented by the following Given that DPF is constant across measurements within a channel, these indices were independent of DPF as it was included in both the numerator and denominator (see Eq.…”

Strategy in short-term memory for pictures in childhood: A near-infrared spectroscopy study

In Baddeley's working memory model, verbalizable visual material such as pictures are recoded into a phonological form and then rehearsed, while auditory material is rehearsed directly. The recoding and rehearsal processes are mediated by articulatory control process in the left ventrolateral prefrontal cortex (VLPFC). Developmentally, the phonological strategy for serially-presented visual material emerges around 7 years of age, while that for auditory material is consistently present by 4 years of age. However, the strategy change may actually be correlated with memory ability as this usually increases with age. To investigate the relationship between the strategy for pictures and memory ability, we monitored the left VLPFC activation in 5 to 11 year-old children during free recall of visually- or auditorily-presented familiar objects using event-related near-infrared spectroscopy. We hypothesized that the phonological strategy of rehearsal and recoding for visual material would provoke greater activation than only rehearsal for auditory material in the left VLPFC. Therefore, we presumed that the activation difference for visual material compared with auditory material in the left VLPFC may represent the tendency to use a phonological strategy. We found that the activation difference in the left VLPFC showed a significant positive correlation with memory ability but not with age, suggesting that children with high memory ability make more use of phonological strategy for pictures. The present study provides functional evidence that the strategy in short-term memory for pictures shifts gradually from non-phonological to phonological as memory ability increases in childhood.

“…Previous clinical studies have also demonstrated that left-lateralization of memory for verbal material is more easily observed than the right-lateralization of memory for non-verbal stimuli (Boucher et al, 2015; Lee et al, 2002; Vaz, 2004; Vingerhoets et al, 2006). Nevertheless, a study using functional near-infrared spectroscopy during a recognition task with abstract shapes has recently reported a right-lateralization of the repetition effect over the right ventrolateral prefrontal cortex (Sanefuji et al, 2007). It is possible that the relatively poor spatial resolution of scalp ERPs compared to functional near-infrared spectroscopy makes it more difficult to detect a right-lateralized repetition effect for abstract pictures.…”

Recognition memory for concrete, nameable pictures is typically faster and more accurate than for abstract pictures. A dual-coding account for these findings suggests that concrete pictures are processed into verbal and image codes, whereas abstract pictures are encoded in image codes only. Recognition memory relies on two successive and distinct processes, namely familiarity and recollection. Whether these two processes are similarly or differently affected by stimulus concreteness remains unknown. This study examined the effect of picture concreteness on visual recognition memory processes using event-related potentials (ERPs). In a sample of children involved in a longitudinal study, participants (N = 96; mean age = 11.3 years) were assessed on a continuous visual recognition memory task in which half the pictures were easily nameable, everyday concrete objects, and the other half were three-dimensional abstract, sculpture-like objects. Behavioral performance and ERP correlates of familiarity and recollection (respectively, the FN400 and P600 repetition effects) were measured. Behavioral results indicated faster and more accurate identification of concrete pictures as “new” or “old” (i.e., previously displayed) compared to abstract pictures. ERPs were characterised by a larger repetition effect, on the P600 amplitude, for concrete than for abstract images, suggesting a graded recollection process dependant on the type of material to be recollected. Topographic differences were observed within the FN400 latency interval, especially over anterior-inferior electrodes, with the repetition effect more pronounced and localized over the left hemisphere for concrete stimuli, potentially reflecting different neural processes underlying early processing of verbal/semantic and visual material in memory.
